To all 'whontit'may concern} Be it known that w.e, Josn1 n A. M sTEE andALBERT ;F. .MUSTEE, citizens of the United States, residing, athQleveland, Cuyahoga county, State of Ohio, have invented certain new anduseful Improvements in Instantan'eous Water-Heaters; and we do declarethat the followingis, a full, clear, and exact description of theinvention, which will enable others skilled in the art-to which itappertains to make and use the same.

Our invention relates to instantaneous water-heaters; and the inventionconsists in the,

or casing sectioned away. Fig. 2 is a sectional plan view of one of theheater-sections, and Fig. 3 is a vertical cross-section of onefiof theheater-sections. 1 if]? The heater thus shown is of the class adapted toheat water instantaneously or practically as soon as the heat has beenapplied, so that heated water may be drawn quickly instead of Waitingfor a time and continuously while the heat is on. ,To this end theheater is constructed with a series of sections or subdivided chambers Aof five-foil or five-leaf formation inplan and connected up at theircenter in acolumn, as seen in Fig. 1. Each leaf a, so called, is spacedapart from the-other well in toward the center of the section, so as toafford circulating-space for the heat between the leaves and fromsection to section, it being understood that to get the best effect inthis particular it is desirable to stagger the sections in the columnEach section is further peculiar in this that in addition to its leafformation there is a central vertical tu bular portion 2 extendingthrough the section from top to bottom and in this instance pro-' ofsaid diaphragm and from the leaf next and last before the leaf havingthe inlet-port. Then as a further feature there is avertical web 8,which projects centrally out into each leaf from tubular hub 2 nearly tothe outer wall of said leaf, but short enough to allow a free flow ofwater around the end of the web through passage 9 from theoutward-flowing subdivision 0 of the leaf to the inward-flowingsubdivision d thereof. The web 8 is cast integral with the body ofsection A along all its edges and spans its leaf. from side to side aswell as being integral with hub 2. It follows from this constructionthat all the water must traverse every leaf of every section forward andreturn before it can make its exit to the next higher or lower one, andthe water flows from one leaf to another in a section around the point10, to which the walls of the leaves converge and where they meet apartfrom hub 2 a sufficient distance to afford a fluid-passage from one leafto another. Then as the water returns through the last leaf andsubdivision d thereof it flows out through exhaust-opening 7 overdiaphragm 5 and thence up into the next section, where the samecircuitous route is taken, and so on.

'In the foregoing paragraph it is assumed that the water is travelingupward in the heater from inlet 12 below to outlet 14 at the top; but insome cases a reverse circulation is established, and the water flowsdownward instead within limits, as will now be seen.

Thus in Fig. 1 we show an outside watercolumn G, tapped at its ends intothe lower and upper sections, respectively, and a faucetc is shown atthe top of said column or pipe, but it might be below as well. We alsoprovide a cut-off valve 15 in this column, so as to close it atpleasure. When this column is open,'we are enabled to establish aneasier line of communication with the top section A than through theresistance within the heater, and

so it follows thatthe heated water in the lower section next to burner Bmay be taken off by column 0 directly to the upper section and outthrough pipe 14 for use or be drawn off by faucet 0, while the coolerwater in the next higher sections will tend to gravitate downward andmingle with the supply from the source 12. Of course lower section Abecomes heated first and hottest, as it is directly over the burner, andit is an advantage of very great value in this heater that the water maybe drawn directly from this lower section when urgently wanted ratherthan to Wait until all the heater and water are brought up to anequally-high temperature.

A suitable shell or casing D incloses the heater-sections and confinesthe products of combustion about the sides thereof, but has a suitableoutlet at the top, and we may use any available kind of burner,according to the kind of fuel; but usually the limitations aremanufactured or natural gas or hydrocarbon oil, gasolene, or kerosene.So, also, any available water-supply may be used from a city main to alocal gravity-feed.

A valve 16 controls the flow of water out through pipe 14, and this maybe more or less closed, especially if it be desired to confine the waterwithin the heater with circulation up through column 0.

Obviously the heater-sections may be of larger or smaller size and asmany may be used as are found available; but more than live or six arenot desirable, because the heat products of combustion become absorbedwithin the limits shown.

The sections A are enlarged somewhat in depth about their centralportion, as seen at a, which gives room for the flow of the fluid in andabout the ducts 6 and 7 and at the point Where the fluid passes from oneleaf or wing into another. This also enables us to make the said leavesin themselves comparatively shallow, so as to get the best possibleexposure to the heat for quick results.

The webs or walls 8 are radially disposed, as shown, with hub 2 as theircenter, and they cut the internal water-space arbitrarily into a longcircuit for the water to travel as it enters opening 6 and passes outthrough opening 7, and the turning-points 9 and 10 in the water-circuitalternate.

Short pipes 0 connect the ends of pipe C with sections A. A web a closesthe waterspace between the first and the last leaf in eachheater-section.

What we claim is 1. In water-heaters, a heater-section constructed witha series of substantially leafshaped portions having a common center andintermediate vertical webs to cause water to travel back and forththrough each portion and from one to another in each section,substantially as described.

2. In water-heaters, a heater-section having a substantially circularoutline and divided up into a series of leaves spaced apart at theiredges and united at a common center, and

said leaves provided each with an intermediate vertical web to cause thewater to circulate from one leaf to another, and separate inlets andoutlets to each series of leaves at its center, substantially asdescribed.

3. A heater-section formed with a series of hollow leaves spaced-apartexternally at their edges toward the center of the section, and the saidsection having ahub at its center extending from top to bottom of thesection, with a division-wall and a central diaphragm therein,an inletfor water on one side of said diaphragm and an outlet for water on theother side thereof, and a wall in said section separating the said inletand outlet, substantially as described.

4. Asection for a water-heating device having a substantially tubularhub constructed to be connected up with another section of the heaterand provided with a diaphragm substantially midway its length and awater-inlet on one side of said diaphragm and an outlet on the otherside, and said section comprising a series of substantially leaf-shapedsubdivisions provided with an intermediate vertical web to cause waterto traverse the entire series of subdivisions from the said inlet to thesaid outlet of the section in reverse directions, substantially asdescribed.

5. The heater-section, substantially as described, having a tubular hubwith threaded extremities and a diaphragm across its center and inletand outlet openings on opposite sides of said diaphragm, and the saidsection having substantially leaf-shaped portions with their wallsconverging toward the center thereof and each portion provided with avertical web subdividing the same part way radially, thereby causing thewater to flow around the end of said web back and forth in each leafportion, substantially as described.

6. In a water-heater, a series of sections arranged one above the otherand connected at their centers and each section having a tubular hubconstructed at its ends to make a close joint with the next adjacentsection, the said hub having a closed central diaphragm and inlet andoutlet openings, respectively, upon opposite sides thereof, and a seriesof vertical radial walls projecting from said hub centrally into saidsection, whereby the water is caused to traverse the entire innerportion of said section from the said inlet-opening to theoutlet-opening, substantially as described.

Witness our hands to the foregoing specification this ltth day of June,1902.
